I updated my computer to 8.1, I lost my SPSWin program, so I reinstalled the program, but cannot find the data. Could you help in finding the data?
If you've formatted the partition where the data was stored, then you will have to use a recovery solution. Luckily, there are plenty applications developed for this operation and a recommended one is Recuva. You can download it through the link posted below. Install the software and use the Wizard to specify the partition where the files were stored and if it's possible the file format. Once you find the files, right click them and choose Restore to, but this time select another partition different than the one were they've found.
